Today we're discussing the impact of urban green spaces on mental health. A recent study in Melbourne followed 500 adults over five years. Participants who lived within 300 meters of a park reported 20% lower stress levels. Interestingly, the size of the park mattered less than its accessibility. Even small gardens, if well-maintained and open to the public, showed benefits. However, the study noted that the effect was stronger for people who visited the space at least twice a week. The researchers suggest city planners prioritize creating networks of small green areas rather than focusing only on large parks.
